Ok Warren
Not sure what the land is like in Tennessee , Andy says he was getting
reliable wspr decodes over 400/500 miles , but that was from -LF- hams
, all the same , with the Ae and power , that's going some ....
thought it was a bit like 500 , where compared to 160 , ground wave
is good to 70 miles
If its a un licensed band how did you get a licence ?
Q what dose the licence say about modes of emission (hint > recent
lofer posts )

Graham,
Yes 2000km is very good for one watt but is not to be expected on a
regular basis!
I have an experimental license that lets me run 10W ERP on 160-190kHz,
my best guess is that with 250W out my ERP is less than 1/2W. Most of
the time 250W is not sufficient to cover 2000km so you can imagine
just how rare a 2000km reception is with 1 Watt !!

1/4 KW ?
Andy is talking about 1 watt dc feed to the PA and a short Ae
, I
thought 2000 kmt was good going for 1 watt
is it the same band ?

I occasionally put a beacon on the 180 kHz band with 250 Watts out and
have been copied in France and the Netherlands during the time each
night that Europe 1 is off.
No magic, about the same results as 137kHz except that 137 is quieter.

Graham,
Have a listen after dark, I seem to remember it was quite horrendous
last
time I looked at that part of the spectrum. I will have another listen
tonight. I think the EU chaps wait until Europe1 has stopped Txing.
Here
is
one frequency I know of, extract from Joe's e-mail.
VO1NA, 184.509.3kHz
TX about 5 watts 0.4 amps to 100m wire at 15 m high.

Ok Gary,
Seems to be some quite big gaps in that spectrum , big enough
for
a cw filter and wspr signal to sit with no splash ?

Nb looks like someone has the spam filter -mal-adjusted- ?

Graham,
I have occasionally read mails on LF regarding U.S. 184kHz qrs beacons
&
captures from Europe. Apparently there is a very powerful broadcast
station
in Europe on a near frequency which causes high qrm when on, I believe
it is
"Europe1"

Lifted from the WSPR web site http://wsprnet.org/drupal/
1 watt and 15 mtrs of antenna ,decoding over 1148 kmtrs , (best
round 2000k) seems to make the 137 attempts look a little 'coy
with
somewhat bigger power levels and rather large arrays , (possibly
mal-adjusted ?)
Is this a band like 500 with enhanced propagation ?
WHAT IS THE POSSIBILITY OF A TA DECODE ?
The frequency range is 160 to 190 KHz. This is most commonly known as
Part-15 operation ( under our FCC Part-15 rules ). The basics: Power
is
limited to 1 Watt DC Input to the Final amplifier, and the antenna
length
cannot exceed 15 meters, including the feed line,
(XR4TN is the experimental call of KU4XR)
